BLIND HINGE AND LOCK.

Specification of Letters Patent.

Patented Nov. 14, 1905.

T0 (0% whom, it may concern: Be it known that I, REUBEN W. PERRY, acitizen of the United States, residing at Lynn, county of Essex, Stateof Massachusetts, have invented a certain new and useful Improvement inBlind Hinges and Locks, of which the following is a specification,reference being had therein to the accompanying drawings.

It is frequently desirable to be able to fasten a shutter or blind sothat it cannot be moved from its position or rattled or shaken by thewind. A device for this purpose should be very strong, so that it willbe able to withstand considerable rough usage, it should be certain inits operation and easy to operate, because it is sometimes necessarythat the shutters or blinds be hurriedly closed, as in case of fire or asuddenly-approaching storm,and it should be cheap, so that it will notadd materially to the expense of the shutter hinges or hangers. Myinvention does away entirely with the fasteners or catches heretofore inuse, thus saving their cost and the labor of putting them up.

My invention also does away completely with the trouble and annoyancesometimes experienced from sparrows or other birds roosting on thefasteners or catches.

The invention is adapted for use on the blinds of dwelling-houses and onfire-shutters, which must sometimes be closed hurriedly; but it isobvious that it may also be used in connection with hinges of allkindsas, for instance, those used on doors and gates.

My invention may also be embodied in a modified form which enables me toapply it to the shutter or blind hangers already in use.

The invention will be fully understood from the following description,in which reference is made to the accompanying drawings, and the novelfeatures thereof are pointed out and clearly defined in the claims atthe end of this specification.

In the drawings, Figure 1 is a view in perspective of a portion of acasing and a shutter hung with a lock-hinge embodying my invention.Figs. 2 and 3 are details of the parts.

Fig. 4 shows a modified form suitable for ap plioation to an old hingeor hanger.

Referring to the drawings, the casing is indicated by A and the shutterby B. A lower hinge member 0 is driven into the casing in the properplace and is provided with the usual pintle 1, upon which the upper ormovable hinge member D swings. The lower hinge member is provided withone or more braces 2, which help to carry the weight and keep the hingemember C from sagging or getting out of true. The parts of the hingemember C which have thus far been described may be of any convenientshape and form nopart of my invention. On the under side and front ofthe fixed member 0 and below the pintle 1 I provide a series of notches8 of considerable depth and slightly wedge-shaped in form.

The second or movable member D is attached to the shutter in the usualway, as by the screws 3, and is provided at the side with a tubularportion 4 for engagement with the pintle l of the lower or fixed hingemember 0 and at the bottom with a second tubular portion 5 at rightangles with the tubular portion 4 and offset, as shown in Fig. 2. Thetop of this tubular portion 5 is on a level with the tops of the notches8 in the fixed hinge member C. This hinge member D may be made from somesuitable sheet metal bent into the desired shape, as shown in thedrawings, or, if preferred, may be cast. The shutter is cut awayslightly to receive this lower tubular portion 5, as shown in Fig. 1. Inthis tubular portion 5 I place the bent locking-lever E, which isprovided with a handle 6 and a point or finger 7, Which engages with oneof the notches 8 in the fixed hinge member C. The looking-lever E turnsabout the portion within the tubular portion of the hinge member D as apivot, and thus moves the point 7 into or out of engagement with thenotch 8 in the fixed hinge member (J. The handle 6 is made of sufficientweight so that the locking-lever is normally in the position shown inFig. 1, with its point in engagement with one of the notches in thefixed. hinge member C. The notches, as previously stated, are madeslightly wedge-shaped, so that the jarring of shutter tends to cause thepoint of the locking-lever to work farther up into the notch and holdthe shutter more firmly, thus preventing all rattling.

When it is desired to move the blind from one position to another, thelocking-lever E is lifted by its handle to the position shown in dottedlines in Fig. 1, thus disengaging the finger 7 from whichever notch 8 itis resting in. The blind is then swung to the desired I the shutter.

When it is desired to use my inventionin connection with the ordinaryform of hanger, as shown in Fig. 4, I provide a washer 10, having a holesuitable for the reception of the pintle 16 of the hanger and havingdepending projections 11, forming notches 12, similar to those describedin connection with Fig. 1. One of these notches 12 passes down over thearm 15 of the hanger, and this prevents the rotation of the washer underthe pressure of the blind. The point 7 of the locking-lever engages thenotches in the same Way as heretofore described.

What I claim is- 1. A lock-hinge comprising a fixed hinge memberprovided with notches upon its under side, a movable hinge member, arock-shaft pivoted to the said movable hinge member and provided with afinger extending below the said fixed hinged member and engaging one ofthe said notches therein.
